NearLink (Chinese: 星闪; also known as SparkLink and formerly Greentooth) is a short-range wireless technology protocol, which was developed by the NearLink Alliance, led by Huawei to set up on September 22, 2020.[1][2] As of September 2023, the Alliance has more than 300 enterprises and institutions on board, which include automotive manufacturers, chip and module manufacturers, application developers, ICT companies, and research institutions.[3][4]
On November 4, 2022, the Alliance released the SparkLink Short-range Wireless Communications Standard 1.0, which incorporates two modes of access, namely, SparkLink Low Energy (SLE) and SparkLink Basic (SLB),[5][6] to integrate the features of traditional wireless technologies, such as Bluetooth and Wi-Fi, with enhanced prerequisites for latency, power consumption, coverage, and security.[7][4][8]
The Alliance unveiled the Standard 2.0 on March 30, 2024, which enhances end-to-end protocol system and extends application standards, supporting native audio and video capabilities, human-computer interaction, and positioning applications.[9]
NearLink employs the Cyclic Prefix-Orthogonal Frequency Division Multiplexing (Cyclic Prefix-OFDM) waveform to address latency issues in various applications. The waveform features an ultra-short frame structure and a flexible scheduling scheme of time-domain resources, reducing transmission latency to approximately 20 microseconds. In addition, NearLink applies polar codes and adopts Hybrid Automatic Repeat-reQuest (HARQ) schemes to support applications with high reliability requirements, such as industrial closed-loop control applications for automated assembly lines, where reliability requirements are at least 99.999%.[1]
The first product to feature NearLink technology was the Huawei Mate 60 series smartphone introduced by Huawei on August 29, 2023,[10][11] followed by FreeBuds Pro 3 on November 25, 2023, M-Pencil 3rd gen with the MatePad 13.2 tablet on 14 December 2023,[12][13] and the Pura 70 series on April 18, 2024.[14][15]
